![[I-Flipper Zero] ilahla i-Raspberry Pi futhi sizenzele ibhodi lethu kusukela ekuqaleni. Ukuthola i-chip ye-WiFi elungile](https://prohoster.info/wp-content/plugins/wp-fastest-cache-premium/pro/images/blank.gif)
- iphrojekthi ye-multitool ephaketheni yabaduni ku-Tamagotchi form factor, engiyithuthukisayo nabangane. Okuthunyelwe kwangaphambilini .
Kuningi okwenzekile kusukela eposini lokuqala mayelana ne-flipper. Besisebenza kanzima sonke lesi sikhathi futhi iphrojekthi ibe nezinguquko ezinkulu. Izindaba eziyinhloko ukuthi sinqume ukuyishiya ngokuphelele i-Raspberry Pi Zero futhi senze ibhodi yethu kusukela ekuqaleni ngokusekelwe ku-chip ye-i.MX6. Lokhu kwenza intuthuko ibe nzima kakhulu futhi iwuguqule ngokuphelele umqondo, kodwa ngiqinisekile ukuthi iwufanele.
Futhi, asikakayitholi i-chipset ye-WiFi elungile esekela yonke imisebenzi edingekayo yokuhlaselwa kwe-WiFi, kuyilapho isekela ibhendi ye-5Ghz futhi ingaphelelwa isikhathi ngeminyaka engu-15. Ngakho-ke, ngimema wonke umuntu ukuthi abambe iqhaza ocwaningweni lwethu.
Esihlokweni ngizokutshela ukuthi kungani senze lesi sinqumo, iphrojekthi ikusiphi isigaba, imisebenzi yamanje, nokuthi ungabandakanyeka kanjani.
Kungani i-Raspberry Pi Zero ingalungile?
Mina ngokwami ββngiyayithanda i-Raspberry Pi, kodwa ngesikhathi senqubo yokuthuthuka kwavela ukuthi yancela izizathu eziningi. Into ebaluleke kakhulu ukuthi awukwazi ukuyithenga. Ngisho nabasabalalisi abakhulu abanazo izingcezu ze-rpi0 ezingaphezu kwamakhulu ambalwa esitokweni, futhi izitolo ezifana ne-Adafruit ne-Sparkfun azithengisi ucezu olu-1 ngesandla. Yebo, kukhona izimboni eziningana ezikhiqiza i-rpi0 ngaphansi kwelayisensi evela ku-Raspberry Pi Foundation, kodwa futhi azikwazi ukuthumela amaqoqo ezicucu eziyizinkulungwane ezi-3-5. Kubukeka sengathi i-rpi0 ithengiswa ngentengo esondelene nezindleko futhi ihloselwe kakhulu ukwazisa inkundla.
Nazi izizathu eziyinhloko zokushiya i-rpi0
- Ayikwazi ukuthengwa ngobuningi. Amafekthri afana noFarnell athembisa ukuthenga i-Compute Module. AmaShayina avela e-Alibaba amanga ngokuba khona kwamavolumu amakhulu, kepha uma kukhulunywa ngeqoqo langempela, ayahlangana. Kuwo wonke umuntu obhala ukuthi asizange siseshe kahle, zama ukuxoxisana nomuntu ukuze athenge izingcezu eziyizinkulungwane ezingu-5, ukuze akuthumelele i-invoyisi yokukhokha.
- Ukuxhumana okumbalwa.
- Iprosesa endala ye-BCM2835, eyasetshenziswa kunguqulo yokuqala ye-rpi. Kuyashisa futhi akuwongi kakhulu amandla.
- Akukho ukuphathwa kwamandla, awukwazi ukulalisa ibhodi.
- I-WiFi eyakhelwe ngaphakathi ephelelwe yisikhathi.
- nezinye izizathu eziningi.
I-Raspberry Pi Foundation ngokwayo iphakamisa ukusebenzisa i-RPi Compute Module emisebenzini enjalo. Leli ibhodi ku-SO-DIMM module form factor (njenge-RAM kumakhompyutha aphathekayo), elishuthekwa ebhodini lomama. Lolu khetho alufanelekile kithi, njengoba lukhulisa kakhulu usayizi wedivayisi.
I-Raspberry Pi Compute Module - ibhodi lesici semojuli ye-SO-DIMM ukuze lifakwe kudivayisi yakho
Sabe sesiqala ukubheka ama-SoM ahlukene (System on Module), amamojula asekelwe ku-i.MX6 abukeka ekhanga kakhulu. Konke ukusesha kwethu kuchazwe kuchungechunge lwenkundla. Kodwa udinga ukukhumbula ukuthi akuzona zonke izinkampani ezizobe zilungele ukusebenza nawe ngenani lezingcezu eziyizinkulungwane ezingu-3-5 ngonyaka. Isibonelo, i-Israel Variscite ivele iyeka ukusiphendula lapho ithola amavolumu okuthenga ahleliwe. Ngokusobala, abanantshisekelo yokuvele bathengise ama-SoM ngaphandle kwezinsizakalo ezengeziwe ngendlela yokusekelwa nokuhlanganiswa. Ngingathanda ikakhulukazi ukubalula unjiniyela waseRussia , ezenza amadivaysi athakazelisa kakhulu, njenge . Cishe akunakwenzeka ku-Google, futhi bengingeke ngazi ngobukhona bazo ukube abangani bami abazange bangitshele.
Ngenxa yalokho, ngemva kokuqhathanisa zonke izinketho nokulinganisa ezomnotho, senze isinqumo esinzima sokwenza i-SoM yethu isuka ekuqaleni iqondise i-Flipper ngokusekelwe ku-chip. . I-single-core Cortex-A7 egijima ku-900 MHz ecishe ifane ne-rpi0, nokho icishe ibanda ngaphansi komthwalo, kuyilapho i-rpi0 ishisa njengesitofu.
Ngokwenza ibhodi yethu kusukela ekuqaleni, sinenkululeko ephelele ekuhleleni izakhi ebhodini, yingakho silindele ukuthola idivayisi ehlangene kakhulu. I-i.MX6 ULZ inguqulo ekhishiwe ye-i.MX6 ULL ngaphandle kwezinye izixhumi ezibonakalayo nomnyombo wevidiyo, ngakho-ke ekuthuthukisweni sisebenzisa i-devboard ye-MCIMX6ULL-EVK nge-chip ye-i.MX6 ULL, ngaphandle nje kokusebenzisa ezinye izixhumi ezibonakalayo. Leli bhodi, ngendlela, lisekelwa i-Linux kernel eyinhloko, ngakho-ke i-Kali Linux enamaphakheji e-kernel ilayishwa kuyo.
Yile ndlela i-flipper ebukeka ngayo ngaphandle kwezingubo okwamanje:
I-WiFi elungile
Ukugebenga kwe-WiFi kungenye yezici eziyinhloko ze-Flipper, ngakho-ke kubaluleke kakhulu ukukhetha i-chipset ye-WiFi efanele ezosekela yonke imisebenzi edingekayo: umjovo wephakethe kanye nemodi yokuqapha. Ngesikhathi esifanayo, ukwazi ukusebenzisa ububanzi be-5GHz namazinga esimanje afana no-802.11ac. Ngeshwa, ama-chips anjalo awatholakalanga ngokushesha
Imojula yesiShayina ye-SiP (isistimu ephaketheni) i-Apmak AP6255 esekelwe ku-BCM43456
Njengamanje sicubungula abantu abaningana, kodwa bonke badinga ukuqedwa futhi akwaziwa ukuthi iyiphi engcono engayikhetha. Ngakho-ke, ngicela ngomusa wonke umuntu oqonda i-WiFi poker ukuthi ajoyine usesho lwethu lapha:
Amakhandidethi amakhulu:
- I-Broadcom/Cypress BCM43455 noma i-BCM4345 ene-firmware enamathiselwe.
- I-Mediatek MT7668 - ingakahlolwa, kodwa ngombono ingase ifaneleke.
Sicela, ngaphambi kokweluleka noma yini, funda ngokucophelela izidingo esithangamini, kufaka phakathi isikhombimsebenzisi sokuxhuma. Khumbula ukuthi ngifunde ngokucophelela lesi sihloko izinyanga ezimbalwa futhi sengivele ngamba yonke into engatholakala.
Yini elungile
Yonke ingxenye lapho i-STM32 inesibopho sayo isivele isebenza: 433Mhz, iButton, i-emulation yokufunda 125kHz.
Ingxenye yomshini, izinkinobho, ikesi, izixhumi, isakhiwo okwamanje singaphansi kokuthuthukiswa okusebenzayo, kuvidiyo nezithombe ezingaphansi kwekesi eliphelelwe yisikhathi, ezinguqulweni ezintsha induku yokudlala izoba nkulu.
Ividiyo ibonisa ukuboniswa okulula kokuvula umgoqo usebenzisa ukudlala kabusha kwesiginali yesilawuli kude.
Imibuzo Evame Ukubuzwa
Ungayithenga kanjani?
Ngokunokwenzeka, sizokwethula umkhankaso wokuxhasa ngemali abantu abaningi ku-Kickstarter ngo-Ephreli-Meyi walo nyaka. Sithemba ukuthumela amadivayisi aqediwe ezinyangeni eziyisithupha ngemva kokuqedwa kokuqoqwa. Uma unentshisekelo kudivayisi, ngikucela ukuthi ushiye i-imeyili yakho ngezansi , sizothumela okunikezwayo kwababhalisile uma ama-prototypes namasampuli angaphambi kwesikhathi alungele ukuthengiswa.
Kusemthethweni?
Leli ithuluzi lokucwaninga. Zonke izingxenye zayo zingathengwa ngokwehlukana esitolo. Uma wakha i-adaptha ye-WiFi kanye nesidluliseli esingu-433MHz ekesi elincane futhi wengeza isikrini lapho, ngeke kusaba emthethweni. Idivayisi ayiweli ngaphansi kwencazelo ekhethekile. indlela noma ithuluzi lokuqoqa ulwazi ngokuyimfihlo. KUPHELA akukho emthethweni ukuyisebenzisela inhloso yokudala umonakalo noma imisebenzi engekho emthethweni. Ngamanye amazwi, ngingenza imimese yanoma isiphi isimo futhi nganoma iyiphi insimbi, umthwalo wokusebenzisa imibese yami ukuwe.
Unganikela kanjani?
Okwamanje ungangisekela mathupha ngeminikelo encane yokudla ngokusebenzisa . Iminikelo evamile ye-$1 ingcono kakhulu kunesamba esikhulu ngesikhathi ngoba ikuvumela ukuba ubikezele kusengaphambili.
Ngishicilela wonke amanothi kuphrojekthi esiteshini sami seTelegram .
